RANGE-BOILER.

SPECIFICATION forming part of Letters Patent No. 595,545, dated December 14, 1897.

Application filed May 19,1897. Serial No. 637,199. (No model.)

as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my present invention is to provide a domestic or range boiler'for hot water of simple, strong, and durable construction, easily manufactured, and not liable to get out of order.

The invention consists in the domestic or range boiler and in the combination and arrangements of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings,

I in which like letters of reference indicate corresponding parts in each of the several views,'Figure' 1 is a front elevation of a ran geboiler provided with my improvements, certain portions being broken away to better illustrate the nature of my said invention; Fig. 2, an enlarged detail sectional view of a portion of the boiler and the head arranged thereon; and Figs. 3 aud t views similar to Fig. 2, illustrating slight modifications thereof.

In said drawings, or represents the cylindrical boiler, provided near each end with an annular shoulder 1), formed by said boiler and embedded in said layer of solder, as illustrated in Fig. 4. The enlarged end portion a is strengthened by an annular band or ring f, preferably bearing against the layer of solder e. I

In the modification illustrated in Fig. 3 the annular shoulder 19 is formed by the cylindrical boiler a and by the outwardly and inwardly curved end portion a which latter bears against and thus surrounds the larger portion of the strengthening rod or wire f. In this construction the sides of the cap or head and of the surrounding band or ring conform to the shape of the bent end portions a as clearly illustrated in said Fig. 3.

The modification in Fig. 4 conforms to the construction illustrated in Fig. 2, with the exception that an annular ring or flange 0 projects from the inner portion of the cap or head a and rests between the enlarged end portion a of the cylindrical boiler and the strengthening-ring f, which for that purpose is provided with an annular shoulder f The inlet and outlet pipes g and h and the circulating-pipes 1 and k are connected with the boiler in the usual and well-known manner, as will be manifest.

The boiler above described is preferably made or spun out of copper, and the head and band is spun upon the ends thereof to conform to the shape of the latter.

Boilers thus constructed are very strong and are easily and quickly manufactured and stand a great deal of pressure, besides having the advantage that should it be necessary to remove the heads of said boiler it can be easily accomplished without injury to the boiler.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1.. A boiler consisting of a cylindrical body provided near its end with an annular shoulder, a strengthening-ring in the end portion of the boiler, a cap on said end portion and bearing with its annular flange upon said end portion and with its inwardly -bent flange against the shoulder in the bodyof the boiler, said annular flange and inwardly-bent flange of the cap conforming to the shape of the end portion of the boiler and its shoulder respectively, and an annular band or ring surrou nding the cap and conforming to the shape of latter and provided with an inwardly and downwardly bent flange bearing against the inwardly-bent flange of the cap and against the adjoining portion of the cylindrical body of the boiler respectively, substan tially as and for the purposes described.

2. A boiler consisting of a cylindrical body provided near its end with an annular shoulder, a strengthening-ring in the end portion of the boiler, a cap on said end portion and bearing with its annular flange upon said end portion and with its inwardly-bent flange against the shoulder in the body of the boiler, said annular flange and inwardly-bent flange of the cap conforming to the shape of the end portion of the boiler and its shoulder respectively, an annular band or ring surrounding the cap and conforming to the shape of the latter and provided with an inwardly and downwardly bent flange bearing against the inwardly-bent flange of the cap and against the adjoining portion of the cylindrical body of the boiler respectively, and a layer of solder covering the bottom of the cap and having the end portion of the boiler embedded therein, substantially as and for the purposes described.

8. A range-boiler consisting of a cylindrical body provided near its end with an annular shoulder, a strengthening-ring within the end portion of the boiler and conforming to the shape thereof, a cap on the said end portion and bearing with its inwardly-bent flange against the annular shoulder of the boiler, an annular ring projecting inwardly from said head or cap and engaging between the end portion of the boilerand the strengthening-ring, substantially as and for the purposes described.

4. A range-boiler consisting of a cylindrical body provided near its end with an annular shoulder, a strengthening-ring within the end portion of the boiler and conforming to the shape thereof, a cap on the said end portion and bearing with its inwardly-bent flange against the annular shoulder of the boiler, an annular ring projecting inwardly from said head or cap and engaging between the end portion of the boiler and the strengthening-ring, and a band or ring surrounding said cap or headand conforming to its shape and bearing with its annular flange against the body of the boiler, substantially as and for the purposes described.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of May, 1897.
